Abstract
An electric fusion furnace for a vitrifiable charge wherein the fusion energy of the furnace is dissipated by the Joule effect in the molten mass, comprising a furnace having electrodes vertically disposed therein which are attached to the bottom of the hearth of the furnace and which are distributed regularly over the entire surface of the hearth in at least one ordered grouping of two rows with each row comprised of three equidistant electrodes powered in three respective phases designated as R, S, and T, wherewith the order of the phases in the two rows is inverted (R, S, T, and T, S, R), such that the two middle electrodes are in phase and the pairs of electrodes on the respective ends are in different phases, and wherewith the interelectrode distance in a given row is approximately equal to the distance between the two rows.
